I also experienced more flakes in Russia, meaning I had to get more numbers to schedule one date than in Ukraine.

I stayed in Moscow for 12 days and spent $2700 (that included $100 a day in lodging from Airbnb).
All in all, the experience was ok, worth a try I think, if not for the potential of witnessing a lewd sex act alone.
Funnily enough, my buddy actually got a match with the hottest one there, who was 15 years his junior (which is why you sly old expats love Russia so much!
Even a date to a basic cafe for coffee and cake will cost you about $25, as opposed to $8 in Ukraine.
